Relating to, intended for, or having the purpose of complete removal or destruction of something.
Formed from extirpate with the adjectival suffix -ory, meaning 'serving to' or 'relating to' the action of extirpation, following Latin-based English adjective patterns.
The suffix -ory (as in 'extirpatory') gives a legal or formal tone—you'll see it in technical writing like 'extirpatory measures' to describe official policies designed to completely eliminate something, which sounds more official than just saying 'removal.'
